Many researchers have emphasized the connection between teachers' thinking and their autobiography, noting that much of teachers' knowledge of teaching has been derived from their life experiences. Since teachers have spent many years watching teachers teach, those experiences become part of the process of learning to teach. This article examines the role of former or remembered teachers in the shaping of the beliefs and practices of eleven successful African-American teachers who teach in urban schools in a major metropolitan area. Both the remembered teachers and the teachers in this study used their pedagogy to enable their students to achieve in spite of circumstances that often militated against success.  相似文献

The development of a set of religiously integrated schools in Northern Ireland since 1981 is often portrayed in wholly positive terms. However, the continued growth of the movement has generated serious tensions at a number of levels which have wider implications for any analysis of the implications of parental choice.  相似文献

In this study, we examined whether reward contrast influences choice between delayed and probabilistic outcomes. Specifically, we predicted that the subjective value of an intermediate reward would seem relatively larger or smaller, respectively, if it followed choices involving a smaller or larger reward and would produce corresponding changes in rates of delay and probability discounting. In Experiment 1, subjects made choices about hypothetical 5,000 or5,000 or 50 outcomes and then made choices about 500 outcomes. Delay-discounting rates for the500 outcomes. Delay-discounting rates for the 500 outcome were larger for Group 5,000 than for Group5,000 than for Group 50, whereas the opposite result was obtained for probability-discounting rates. In Experiment 2, we used a design that allowed for contrast effects to be assessed within subjects. Two groups made choices about delayed or probabilistic rewards. After completing question blocks in which the amount was 5,000 or5,000 or 50, subjects responded to questions with an intermediate amount (475/475/525). For Group Delay, the present value of the intermediate reward was greater after the 50 block than after the50 block than after the 5,000 block, whereas the opposite was obtained for Group Probability. The results from both experiments confirmed the predictions of reward contrast and suggested that the subjective value of a monetary reward varies inversely with the prior reward amount.  相似文献

This study investigated whether competitive and noncompetitive educational mathematics computer games influence four‐ to seven‐year‐old boys’ and girls’ recall of game‐playing experience. A qualitative analysis was performed to investigate what preschool children may have learned through their selective recall of game‐playing experience. A difference emerged in six‐ to seven‐year‐old boys’ and girls’ recall after playing a competitive computer mathematics game, such that boys tended to first recall the consequence of ‘winning and losing’ whereas girls of the same age focused on ‘friendship among animated characters’ in the game. Thus, the qualitative results suggest the possibility that selective attention or selective recall might be partially influenced by gender schemas. Based on the recall sequences, educational noncompetitive computer mathematics games may lead to a better learning outcome for older boys.  相似文献

Many theories of giftedness either explicitly or implicitly acknowledge the role of genetic influences; yet, empirical work has not been able to establish the impact that genes have specifically on gifted behavior. In contrast, a great deal of research has been targeted at understanding the etiology of individual differences in general and specific cognitive abilities across the entire range of ability and to a lesser extent, high cognitive ability. This paper attempts to outline what we know and what we don't know about the etiology of giftedness as operationally defined as high g. We review studies selected to represent a variety of approaches that each address a different question about genetics and giftedness. These studies include quantitative genetic research which estimate heritability, shared and nonshared family environment – at the high and low ends of intelligence – as well as the heritability of group differences for general cognitive ability and specific cognitive abilities. We discuss the molecular genetic methods and mechanisms contributing to cognitive ability and suggest how epigenetic factors may operate. Quantitative and molecular genetic studies that include endophenotypes representing intelligence at a level closer to the genotype, are also included. This last group of studies represent a relatively new area of work that builds on and extends the extensive groundwork established by classic quantitative genetic studies of behavior.  相似文献

Using data from the National Early Head Start (EHS) Research and Evaluation Project (N = 1851), the current study examined relations among cumulative family and social risk, assessed during infancy and the preschool years, and children's prekindergarten achievement, self-regulatory skills, and problematic social behavior, testing if these associations were mediated through two sets of family processes–responsive parenting practices and the provision of language stimulation and literacy practices. Structural equation modeling results highlight the significance of the timing of children's experience of risk in predicting school readiness competencies. Risk exposure during infancy was observed to be most detrimental for children's school readiness skills and was partially mediated by risk exposure during the preschool years and family processes, assessed during toddlerhood and the preschool years. Moderation analyses revealed no difference in the strength of relationships among the study variables by EHS assignment or by race/ethnicity.  相似文献

The objectives of this study were twofold: to examine the interaction of academic stress and student resourcefulness on subject grades and to identify the factors of parental support that contribute to student resourcefulness. The participants of this cross‐sectional study were 695 fifth and sixth graders from four major districts in Shanghai. Student resourcefulness was observed to moderate academic stress and subject grades. Moreover, perceived paternal emotional support and maternal informational support contributed significantly to student resourcefulness. The implications of this study for parent education are discussed.  相似文献

To investigate the effects of a single high-load (80% of one repetition maximum [1RM]) set with additional drop sets descending to a low-load (30% 1RM) without recovery intervals on muscle strength, endurance, and size in untrained young men. Nine untrained young men performed dumbbell curls to concentric failure 2–3 days per week for 8 weeks. Each arm was randomly assigned to one of the following three conditions: 3 sets of high-load (HL, 80% 1RM) resistance exercise, 3 sets of low-load [LL, 30% 1RM] resistance exercise, and a single high-load (SDS) set with additional drop sets descending to a low-load. The mean training time per session, including recovery intervals, was lowest in the SDS condition. Elbow flexor muscle cross-sectional area (CSA) increased similarly in all three conditions. Maximum isometric and 1RM strength of the elbow flexors increased from pre to post only in the HL and SDS conditions. Muscular endurance measured by maximum repetitions at 30% 1RM increased only in the LL and SDS conditions. A SDS resistance training program can simultaneously increase muscle CSA, strength, and endurance in untrained young men, even with lower training time compared to typical resistance exercise protocols using only high- or low-loads.  相似文献
